I looked at > http://wiki.apache.org/solr/Join and see no reference to "fromIndex". > Also does this work in a distributed environment? > The "fromIndex" isn't documented in the wiki.... It is mentioned in the issue and you can find in the Solr code: https://issues.apache.org/jira/browse/SOLR-2272?focusedCommentId=13024918&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13024918
The Solr join only works in a distributed environment if you partition your documents properly. Documents that link to each other need to reside on the same shard and this can be a problem in some cases. Martijn
